LOOK FOR FLOOR SAIES.

Application filed November 1, 1926. Serial No. 145,599.

This invention relates to looks for floor safes and a primary object is to provide a simple, economical and efficient type of device adapted to be convenientl located on a-safe which is adapted to be im edded in the floor of a shop, store, oflice or other kind of building, and so arranged that it is incapable of belng tampered with for the purpose of gaining access to the interior.

A still further object is to provide a palr of locks one of which will lock the sliding bolts against operation by the other lock, thus necessitating the operation of both of said locks before access can be gained to the interior of the safe.

Still other objects may appear as the description progresses.

I have shown a preferred embodiment of my invention in the accompanying drawings, subject to modification withln the scope oi the appended claims without departing from the spirit thereof, in which:

Fig. 1 is a top plan view of a floor safe embodying myimprovements.

Fig. 2 is a sectional elevatlon of the same, as seen on line 22 of Fig. 1.

Fig. 3 is a sectional plan of the same on line 33 of Fig. 2.

Fig. 4 is a fragmentary section of the same on line 44 of Fig. 1.

Fig. 5 is a perspective view of the lock housing; and

Figs. 6 and 7 are perspective views of the locking bolts operably supported in the housing shown in Fig. 5

Briefly descri ed, my invention is adaptable to a receptacle havin a cylindrical body B, closed at the bottom by means of a disc D and provided with an annular top T, in which is held a removable cover 0. Said cover is provided on the lower side with a lock housing H which serves to enclose a pair of locking bolts 6 and 6, adapted to be operated and controlled by means of a pair of cylinder locks L and L.

The safe as shown is adapted to be imbedded in a concrete or cement floor, as at F, and the bottom member I) and top member T are of greater diameter than the body member B, so that said bottom and top members will project over the body and the cement will fill the spaces between said top and bottom members, so as to render the safe inca able of removal from the floor. Also, t, 0 bottom member D is constructed preferably in the form of a polygon, with a plurality of sldes 1, 1, etc., eight of such sides being shown in the drawing, so as to revent the turning of the receptacle in the Eoor by accident or design, and to cause the safe to be stationarily held in position.

The body B is formed preferably of round steel tubing of substantial diameter, so as to provide a compartment I in the safe for the reception of money and articles of value. The bottom D is formed of a plate of steel which is preferably attached to the lower end of the body B by arc welding in the fillets f, f, etc. The top T is formed preferably of a piece of carbon-steel plate of substantial thickness, and is likewise attached to the upper end of the body B by welding at thefillets f, f, etc. The top T is provided with a central stepped opening, as at O, which has the largest opening on its upper side and the smallest opening on its lower side, providing a plurality of annular shoulders 2, 2, etc., of different diameter, which are adapted to correspond in size to and to receive a plurality of correspondingly and reversely formed portions 3, 3, etc., formed on the cover C, the larger of the portions 3 being at the top and the smaller of said portions at the bottom of the member C.

As indicated at 4, a gasket of rubber or other suitable substance may be provided between the lowermost shoulders of the members T and G, for the purpose of rendering the receptacle proof against the entrance of water from the floor above, though this is immaterial to my invention.

The cover C has an angularly formed narrow slot S therein, through which money may be deposited in a compartment I of the safe, without removing the cover G. The locking housing H is attached to the lower side of the cover G by means of a pair or more cap screws 5, 5, which are threaded into blind holes 6, 6, in the cover C and extend through apertures 7, 7 in the housing H. Said housing is rectangular in form and has a bottom portionS, with sides 9, 9 and end portions 10 and 11, the edges of the sides, 9,9 and the ends 10 and 11 abutting the lower side of the cover 0.

The ends 10 and 11 of said housing are rovided withjrectan ular openings 12 an 13, respectively, for s 'dably receiving the looking bolts 12 and b, and by meansof which said bolts may be extended from the housing H to ositions beneath the annular top'mem- -ber so as to firmly lock the member'C in position on the member T for closing the compartment I of the safe against unauthorized access.

The locking bolts 6 and b are of rectangular formrand are of substantial cross sectional area, said bolts being transversely disposed across and slidable on the member C on opposite sides of the locks L and L, as shown in Fig. 3. The members 6 and b have recesses 13 and 14 formed in the central portions thereof, which are adapted to receive the end portions e and 6', respectively of a locking member E, which is suitably fixed to the rotating member 15 of the lock L. The member I) is also provided with a recess 16 at its rear end, which receives the end portion 17 of an auxiliary locking member E suitably fixed to the rotating member 18 of the lock L.

The locks L and L are pressed, keyed or otherwise stationarily and irremovably held in the cover G, and the members E and E are fixed to the members 15 and 18, respectively, of said locks by means of ins 19 and 20, or otherwise. The purpose 0 the two locks is to provide a double and extra safeguard against the manipulation of the locking device by unauthorized parties, or by accidental means.

The lock Leis preferably positioned in the center of the cover C, while the supplementary lock L isalined therewith transversely, so that whenit is desired to gain access to the safe it is first necessary to operate the lock L before the lock L can be operated for retracting the bolts 7) and b to permit the removal of the cover C. By reference to Fig. 3,it will be observed that when the cover is locked in position,as shown in said figure, the bolts 12 and b are extended from the opposite ends of the housing H, respectively, so as to underlie the annular member T.

The bolt 0 erating member E attached to the lock L, wiien the lock is turned in a given direction will move the bolts 11 and b in oposite directions for either looking or unlockmg the safe, but when the elements of the lock are in the position shown in Fig. 3, it is first necessary to operate the lock L in a clock-wise direction for retracting the portion 17 of member E so as topermit the retraction of the bolt 6 by the subsequent operation of the lock L. When the cover is locked in position the lock L is operated in a reverse direction from that stated, for extending the bolts b and b from the op site ends of the housing H, and the lock is subsequently operated in a counter-clock-wise direction for moving the portion 17 of member E against the end of the recess 16 in the bolt b.

thorized access, so that it willserve as a safe and convenient means for safeguarding sums of money and articlesof value against unauthorized removal.
